METHOD AND APPARATUS FOR PROVIDING 3D AUDIO
Embodiments of the subject invention relate to a method and apparatus for virtualizing an audio file. The virtualized audio file can be presented to a user via, for example, ear-speakers or headphones, such that the user experiences a change in the user's perception of where the sound is coming from and/or 3D sound. Embodiments can utilize virtualization processing that is based on head rotated transfer functions (HRTF's) or other processing techniques that can alter where the user perceives the sounds of the music file to originate from. A specified embodiment provides Surround Sound virtualization with DTS Surround Sensations software. Embodiments can utilize the 2-channel audio transmitted to the headphones.
1 . A method for virtualizing an audio file, comprising:
receiving a request for a virtualized audio file;
acquiring an audio file, wherein virtualization of the audio file will produce the virtualized audio file;
virtualizing the audio file to produce the virtualized audio file, wherein virtualizing the audio file changes where a user listening to the virtualized audio file perceives sounds from the virtualized audio file originate from compared with the user listening to the audio file; and
providing the virtualized audio file in response to the request.
